Abstract: Simple film preparation method of solution casting has been used for making of biodegradable PVP and Cornstarch blend polymer electrolytes. Ion dynamics in polymer film membranes has been understood by conductivity and dielectric studies. The combination of 60wt% PVA and 40wt% Corn Starch is having the high conductivity value of 1.56 x 10-9 S cm-1 at ambient temperature and when the temperature increases, the conductivity also linearly increases to obtain 4.93 x 10-9 S cm-1 at 363 K which due to ion hopping mechanism in the polymer matrix. The frequency dependence of dielectric permittivity, dissipation factor (tangent loss) and electrical modulus have been used to know about dielectric behaviours of the polymer blend electrolytes. In dielectric studies, Non-Debye behaviour was observed in all samples.
